.PREV DISCUSSION... /issued 323 AM PST Tue Jan 13 2026/

Key Messages...

- Air Stagnation Advisory from 7 AM today through 7 AM PST Friday

- Wind Advisory for Ladd and Pyles Canyons through 2 PM PST today.

DISCUSSION...Sensible, dry weather will continue into the next week
and onward with this ridging pattern. Stagnant air conditions will
also prevail, thanks to low mixing heights (below 1.5 kft) and weak
transport winds (under 10 mph) at Kittitas and Yakima Valleys,
Columbia Basin of WA/OR, the Gorge, north and central OR. That said,
the air stagnation advisory will continue to last through early
Friday morning. In addition to that, fog may redevelop with this
high pressure aloft during early morning and overnight hours in the
valley areas over the next few days, particularly in the
Kittitas/Yakima Valley and portions of the Lower Columbia Basin of
WA. Near to below freezing low temperatures and dew point
depressions may also assist in bringing freezing fog. This can
impact visibilities in those aforementioned areas as well, which
could make traveling difficult during the early morning and
overnight hours.

An wind advisory for Ladd and Pyles Canyons at the Grande Ronde
valley will remain in effect until this afternoon. Wind gusts will
exceed to 30-45 mph with the northwesterly flow aloft. The GFS, NAM,
and SREF show pressure gradients of 4-7 mb for Baker (BKE)- Meacham
(MEH) along with the HREF guidance favoring a 40-50% probability of
wind gusts at 30 mph or higher. While the pressure gradients may
decrease to 3-5 mb, these gusts could linger until around 2 PM or
few hours after. Otherwise, the remaining forecast area will have
mostly light winds with occasional breezes. Feaster/97


AVIATION...12Z TAFS...VFR conditions will continue through the TAF
period for most sites. However, KYKM may see fog develop tonight
whereas VSBY could drop to 1/2SM or lower thus bringing LIFR
conditions (50% confidence). Winds will be less than 10kts.
